Chapters is the ultimate 'guilty pleasure' app for adults that becomes a nightmare in a child's hands. It’s designed to exploit the 'what happens next' urge by hitting you with a paywall right at the climax of a chapter.
The content is often borderline erotica, and the mechanics are built on the same psychological triggers as slot machines. If your teen is looking for interactive fiction, steer them toward '80 Days' or 'Choice of Games'—titles that actually value the story over the credit card swipe.
